4 Claims.

This invention relates to lamps of the type used for flood lighting, asfor example, lighting the exterior of a building. More particularly, thelamp herein described combines a flood light with street lighting lampsof the type usually mounted upon a post, or a pillar. The lamp has twosources of light, one located above the other, the upper light sourcebeing adjustable into different angular positions about an upright axis,

and also about a horizontal axis, in order to direct it for floodlighting purposes. The lower light source is used for illuminating theinterior of the unit, and for general illumination about the support forthe unit.

The invention has for its object, a particularly simple and emcient lampconstruction, whereby the lower lamp can be made readily accessiblethrough the top of the globe frame by shifting the directable upperlamp, and the upper lamp returned to its adjusted position after beingso shifted Without the necessity of readjusting.

Other objects will appear throughout the specification.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings, in which like characters designate corresponding parts in allthe views.

This lamp comprises generally, a base, a globe frame mounted on the baseand having a movable top for permitting access to the interior of theglobe frame and the lamps therein, lamps mounted in the frame, one abovethe other, the upper lamp being adjustable into different angularpositions, one of these adjustments being a tilting movement about ahorizontal axis, and means by which, when the upper lamp is adjusted ina certain position, it can be readily tilted out of such position forthe purpose of removing and replacing the lamp therein, and for thepurpose of removing and replacing the lower lamp below the same and thenmoved back into the exact adjusted position Without any attention on thepart of the operator to accurately relocate it in its adjusted position.

1 designates a hollow base mountable upon a post.

2 designates the globe frame having a, movable top 3 for permittingaccess to the interior of the globe frame.

4 designates generally, a lamp support, this including a disk shapedturn-table 5 rotatably mounted on the base to cover the open top sidethereof, and upwardly extending yoke arms, 6 extending to the upper partof the globe frame.

'7 is a lamp carriage forthe upper lamp mounted betweenthe yoke arms 6on a horizontal axis.

8 is a reflector fixed in any suitable manner to the carriage '7.

9 is a lamp socket, and 10 a lamp socket support secured to the carriage'7.

11 is a lamp having a base extending through an opening 12 in thereflector and into the lamp socket 9.

13 is the lower lamp having its base 14 extending through a centralopening of the turn-table 5, and into a lamp socket 15 carried by asuitable support 16 secured to the turn-table and depending into thebase 1 in order that the wires, which extend through the base, may bereadily secured to the binding posts of the lamp socket 15. The wiresleading to the lamp socket 9 also extendfrom the base through thecentral opening of the turn-table.

The turn-table is adjustable through a col plete circle in order todirect the reflector 8 in a predetermined horizontal radial angle, andis held in its adjusted position by a set screw 17.. The lamp carriage'7 and the reflector are adjustable, as a unit, about a horizontal axisin order to direct the light from the upper lamp in a predeterminedradial angle out of the horizontal and the carriage 7 is held in itsadjusted position by impositive or friction latch means, which permitsit to be temporarily shifted out of its adjusted position in order togive access to either the upper or lower lamp 11 or 13, through the topof the globe frame and then snap back into its present position withoutgiving any attention to the adjustment.

As here shown, one yoke arm is provided with. a member 20 which isshiftable about the pivot 21 of the carriage, this member having an areshaped surface 22 struck from the center 21, and a single notch 23 atthe end of the arc shaped surface 22; and the carriage 7 is formed witha spring pressed or resilient pawl or latch 24 coacting with the notch23 and the surface 22. The member 20 is adjustable about the pivot 21 toany predetermined angular position and is held in its position by aclamping screw 25 extending through an arc shaped slot in the member 20and threading into one of the yoke arms 6. Thus, when the angularposition of the lamp carriage 7 is determined, the member 20 is adjustedso that the pawl 24 engages the notch 23 and thus, upon movement of thecarriage about its pivot, the latch will move out of the notch along thesurface 22 and then when the carriage is shifted back, the latch willagain re-engage the notch 23 and the lamp carriage will be locatedexactly in the same angular position as before.

This latching means is particularly advantageous in that both the lamps11 and 13 are accessible through the upper top of the globe frame, andwhen it is necessary to remove and replace either one of the lamps, itis necessary to tilt the carriage 7, and that the tilting can beeffected without upsetting the accurate adjustment of the angularadjustment of the lamp carriage '7, or rather, the lamp carriage 7 canbe returned to its adjusted position without readjustment. The lampsocket 9 is adjustable axially to locate the lamp filament relative tothe focus of the reflector and as here shown, the socket is carried by ayoke or fork 26 or any other suitable carriage, which is slidablealong aguide as rods 27. The fork 26 is held in its adjusted position bysuitable means as set screws 28.

The globe frame 2 is here shown as polygonal in general form in crosssection, and as in the general form of an inverted truncated cone.

The frame consists of upright spaced frame members 30 with glass panelsbetween them. Each of the frame members is formed with a lengthwise rib31 along the median line thereof, and said rib is formed at intervalswith spaced apart lugs 32. The glass panels 34 rest on the members 30 onopposite sides of the rib and are clamped in position by clampingmembers 35 interlocked with the lugs 32, and overlying the margins ofthe glass panes 34. The clamping members are held in position by screws36 extending through the frame members 30 and the ribs thereof betweenthe lugs 32 and threading into the clamping members. Springs 3'7 areinterposed between the clamping members and the tops of the ribs andbetween the edges of the glass panes 34, the springs encircling thescrews 36. Obviously, upon tightening of the screws, the clampingmembers will be yieldingly pressed against the margins of the glasspanes 34. Suitable packing material 39 is interposed between the marginsof the glass panes 34 and the frame members 30.

The top 3 includes a suitable metallic frame, which is preferably hingedat 40, and one piece conical glass top 41 overlying the frame. The glasstop 41 is clamped to the top frame by means of a centrally locatedclamping nut 42 threading on a stud 43 at the apex of the top frame andthrusting against an outwardly extending hollow hub 44 at the apex ofthe glass 41. A suitable gasket 45 is interposed between the margin ofthe glass 41 and the margin of the top frame. Also, a suitable yieldingpacking material 46 is interposed between the nut 42 and the hub 44. Asuitable gasket 49 is also inserted between the top frame and the globeframe 2. The top frame is held in its closed position by a suitablescrew 50.

In installing these lamps, one gang of workmen mount the base, and globeframe, and top, and the electricians perform the wiring operation andadjust the lamp carriage 7 into the proper angular position and thus,after the workmen have installed the base, and globe frame, the adjustments can be readily made through the open top, although the wireconnections, particularly to the lower lamp, are preferably made byremoving one or more of the glass panels. This can be easily done byreason of the fastening means for the glass panels, the turn-table beingprovided with a suitable work hole for the wiring. The insertion andreplacement of the lamps can be readily made without permanentlyupsetting the angular adjustment of the upper lamp and withoutreadjustment 0f the upper lamp after it has been once adjusted.
